The Schaumburg, Ill.-based communications technology giant said the $3.9 billion deal was formally completed after Tuesday's approval of the deal by Symbol shareholders. They will get $15 per share in the deal.

Motorola and Symbol announced the acquisition on Sept. 19 last year, after Symbol fielded offers from several companies and involved itself in on-again, off-again negotiations with Motorola for more than a year.

Symbol, which has been based in Holtsville, N.Y., will now become part of Motorola Networks & Enterprise group. Motorola has said its Holtsville property will remain open as a center of excellence for enterprise mobility, as well as the hub of those operations. The Networks & Enterprise group will be a $13 billion entity, Motorola said.
